FIG. 1 is an illustration of an example 100 associated with verifying identity of a source of a transmission, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 associated with and/or included within a cyber security service provider (CSP) control infrastructure 104 for purposes of obtaining cyber security services. The CSP control infrastructure 104 may include a secured device 106, a processing unit 110, and a security database 112. A user device may include a source application (e.g., communication application) 114 and a processing unit 116. The user device 102 and/or the CSP control infrastructure 104 may utilize a firewall 118 to communicate with a destination device 108 operating on the open Internet. The destination device 108 may include a destination application 120 and a processing unit 122.

In some aspects, the user device 102 may be referred to as a source device. The source application 114 may include an application utilized by the user device 102 to communicate (e.g., transmit and/or receive) information and/or messages over a network (e.g., Internet). In an example, the source application 114 may include one or more third-party applications such as, for example, a web browser application, an email application, a social network application, a messaging application, or the like. The CSP control infrastructure 104 may be owned and operated by a cyber security service provider. The security device 106 may be configured to receive data communicated by the user device 102 and may be communicatively coupled to the processing unit 110. Additionally, the processing unit 110 may be communicatively coupled to the security database 112, which may be capable of storing data associated with providing the cyber security services.

The user device 102 and/or the destination device 108 may be physical computing devices capable of hosting applications (e.g., source application 114, destination application 120, etc.) and of connecting to the network. The user device 102 and/or the destination device 108 may include, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 and/or the destination device 108 may include, for example, Internet-of-Things (IoT) devices such as MSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. In some aspects, the user device 102 and/or the destination device 108 may include a server computer.

The network may be any wired or wireless digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network may include a combination of one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the cyber security services. The processing unit 110 included in the CSP control infrastructure 104 may be configured to determine the cyber security services to be provided to the user device 102.

The CSP control infrastructure 104 may include a combination of hardware and software components that enable provision of cyber security services to the user device 102. The CSP control infrastructure 104 may interface with (the communication application on) the user device 102 via an application programming interface (API) (not shown), which may include one or more endpoints to a defined request-response message system. In some aspects, the API may be configured to receive, via the network, a connection request from the user device 102 to establish a connection with the CSP control infrastructure 104 for purposes of obtaining the cyber security services. The connection request may include an authentication request to authenticate the user device 102 and/or to receive the cyber security services.

The API may further be configured to handle the connection request(s) by mediating the authentication request. For instance, the API may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API may provide the received credentials to the processing unit 110 for verification. The processing unit 110 may communicate with the security database 112 to authenticate the user device 102.

The security database 112 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The cyber security service provider may add or delete such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API, the user database 108 and a processor (e.g., the processing unit 110 or another local or remote processor) may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the security database 112 and the processing unit 110 may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the cyber security service provider may provide better security services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the cyber security service provider may decline to provide cyber security services to the user device 102.

When the user device 102 is authenticated, the user device 102 may initiate a connection with the CSP control infrastructure 104 for obtaining the cyber security services. The processing unit 110 may utilize the API 106 to transmit information associated with the cyber security services to the user device 102.

One or more components (e.g., security device 106, processing unit 110, and/or security database 112, source application 114, processing unit 116) included in the CSP control infrastructure 104 and/or included in the user device 102, as shown in FIG. 1 , may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 6 ). For instance, the one or more components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more components included in the CSP control infrastructure 104 may be separate and distinct from each other. Alternatively, in some aspects, the one or more of the components included in the CSP control infrastructure 104 may be combined with one or more of the other components. In some aspects, the one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the CSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the CSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory for execution by a processor. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, the one or more components may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

A CSP control infrastructure may provide cyber security services to an associated user device. Providing the cyber security services may include the CSP control infrastructure configuring a firewall to provide network security by monitoring and filtering data communicated (e.g., transmitted and/or received) by the user device over the open Internet. Configuring the firewall may include establishing the rules according to which the firewall may filter the data. The data may be communicated utilizing an internet protocol (IP) packet that indicates source information (e.g., source IP address, source port, etc.) associated with a source of the IP packet and destination information (e.g., destination IP address, destination port, etc.) associated with a destination of the IP packet. The firewall may be configured to allow communication of IP packets including specified source information and/or destination information.

For instance, the user device may transmit an IP packet via the firewall to a destination device on the open Internet. The firewall may be configured to allow transmission of the IP packet from the user device to the destination device based at least in part on specifying, in an established rule, the source information associated with the user device and the destination information associated with the destination device. In this case, upon receiving the IP packet, the firewall may allow transmission of the IP packet to the destination device based at least in part on the established rule.

In some cases, the network security provided by the firewall based on the established rule may be inadequate. For instance, a malicious party may gain unauthorized access to the user device and may install connection malware on the user device. In this case, when the user device transmits the IP packet to connect with the destination device, the firewall may allow transmission of the IP packet according to the established rule. Due to the connection malware, the IP packet may include malicious content, which when received by an external device (e.g., the destination device and/or another device) on the open Internet, may enable the malicious party to connect with and/or gain unauthorized access to the CSP control infrastructure.

In an example, the malicious party may install system malware on the devices associated with the CSP control infrastructure (including the user device). The system malware may be designed to disrupt and/or damage operation of the CSP control infrastructure. In an example, the system malware may embed itself within an operating system of the CSP control infrastructure and may execute an unauthorized transmission of private information stored in a database associated with the CSP control infrastructure. In another example, the system malware may execute an unauthorized deletion of data stored in the database. The system malware may also cause other hindrances by adversely affecting the operating system of the CSP control infrastructure such that the operating system may run slower and/or associated circuitry may emit excessive heat and/or noise, thereby causing damage to the devices associated with CSP control infrastructure.

In such cases, the CSP control infrastructure may expend various infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) in efforts to mitigate effects of the private information becoming compromised and the hindrances caused by the system malware. Similarly, the user device may expend various user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) in efforts to mitigate effects of the private information becoming compromised and the hindrances caused by the system malware.

Various aspects of systems and techniques discussed in the present disclosure enable verifying identity of a source of a transmission. In some aspects, as shown in FIG. 1 , a CSP control infrastructure may configure a security device to verify an identity of a source application, as discussed herein. In some aspects, an associated user device may utilize the source application to transmit an IP packet via a firewall to a destination device on the open Internet. The security device may receive the IP packet from the source application and may determine connection information included in the IP packet. In some aspects, the connection information may indicate one or more parameters to be used by the user device and the destination device to connect and/or communicate data. The security device may determine a fingerprint associated with the connection information. The security device may compare the determined fingerprint with stored fingerprints, stored in a database associated with the CSP control infrastructure. The stored fingerprints may be associated with trusted source applications that are known to be in a condition unaffected by malware (e.g., connection malware and/or system malware). When the result of the comparison indicates that the determined fingerprint matches a stored fingerprint, the security device may determine that the source application is unaffected by malware. In this way, the security device verifies the identity of the source application as being a trusted source application. In this case, the security device may forward the IP packet to the firewall. Alternatively, when the result of the comparison indicates that the determined fingerprint fails to match the stored fingerprint, the security device may determine that the source application is affected by malware and/or that the IP packet includes malicious content. In this way, the security device verifies the identity of the source application as being an affected source application. In this case, the security device may discard the IP packet without forwarding the IP packet to the firewall. In other words, the security device may avoid transmission of the IP packet, which includes the malicious content, via the firewall to an external device on the open Internet. In this way, the security device may prevent a malicious party from gaining unauthorized access to the CSP control infrastructure. As a result, the security device may mitigate effects of private information becoming compromised and/or other hindrances. Additionally, the security device may enable efficient utilization of infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and/or user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) for suitable tasks associated with providing the cyber security services.

In some aspects, a processor (e.g., processing unit 110, processor 620, etc.) may receive, from a transmitting source application, a transmission packet to be transmitted to a destination application; determine connection information included in the transmission packet, the connection information indicating one or more parameters to be utilized by the destination application to connect with the transmitting source application; determine a fingerprint associated with the connection information based at least in part on encrypting the connection information; compare the determined fingerprint with a stored fingerprint stored in correlation with an identity of a trusted source application; and process the transmission packet based at least in part on a result of comparing the determined fingerprint with the stored fingerprint.

FIG. 2 is an illustration of an example flow 200 associated with verifying identity of a source of a transmission, according to various aspects of the present disclosure. The example flow 200 may include a user device 102 in communication with a security device associated with a CSP control infrastructure 104 (e.g., FIG. 1 ). In some aspects, the user device 102 may be associated with and/or included within the CSP control infrastructure 104. The user device 102 may utilize a source application to communicate data via a firewall (e.g., firewall 118) with a destination device 108 on the open Internet. In some aspects, the user device 102 and the CSP control infrastructure 104 may communicate with each other over a network (e.g., Internet). As discussed elsewhere herein, the CSP control infrastructure 104 may enable the user device 102 to obtain cyber security services.

In some aspects, the user device 102 may install source applications to be utilized to communicate information and/or messages with destination devices 108 on the open Internet. The source applications may include third party applications such as, for example, email clients (e.g., Outlook application, Gmail application, etc.), web browsers (e.g., Firefox, Chrome, Internet Explorer, etc.), messaging clients (e.g., Slack, Facebook messenger, etc.), social media applications (e.g., Facebook, Instagram, etc.), or the like.

Although only one user device and only one security device are shown in FIG. 2 , the present disclosure contemplates the system to include any number of user devices and security devices that operate in a similar and/or analogous manner as discussed herein.

In some aspects, the user device 102 may obtain cyber security services from the CSP control infrastructure 104. Providing the cyber security services may include the CSP control infrastructure 104 determining stored fingerprint information that is stored in, for example, the security database 112. The stored fingerprint information may include fingerprints associated with trusted source applications that are known to be in a condition unaffected by malware (e.g., connection malware and/or system malware). In some aspects, the CSP control infrastructure 104 may utilize the security device 106 to determine the stored fingerprint information based at least in part on hashing and/or encrypting connection information indicating one or more parameters associated with the trusted source applications.

In an example, during a reference period prior to providing the cyber security services, the security device 106 may receive one or more trusted transmission packets from one or more trusted source applications installed on the user device 102. Such one or more trusted transmission packets may include initial connection packets indicating connection information to be utilized to connect with and/or communicate data with the one or more trusted source applications. Based at least in part on receiving the one or more trusted transmission packets, the security device 106 may determine an identity of the one or more trusted source applications.

In some aspects, determining an identity of a source application may include determining information identifying a state of the source application. In an example, determining the identity of the source application may include determining information identifying the source application. As discussed herein, the identity of the source application may be utilized to determine a state of the source application as being affected by malware or being unaffected by malware.

For a given trusted transmission packet, the security device 106 may determine source information (e.g., source IP address, source port, etc.) associated with the user device 102. The security device 106 may utilize the source information to query a local Internet protocol (IP) table to determine a process identifier associated with a given trusted source application that transmitted the given transmission packet. Based at least in part on an association between the process identifier and the identity of the given trusted source application, the security device 106 may determine the identity of the given trusted source application.

In some aspects, the given transmission packet may include given trusted connection information to enable the destination application to connect and/or communicate with the given trusted source application. Based at least in part on receiving the given trusted transmission packet, the security device 106 may analyze the given transmission packet to determine the given trusted connection information. In some aspects, the given trusted connection information may indicate information associated with any combination of one or more parameters to be utilized by the given trusted source application and the destination application to connect and/or communicate with each other.

In an example, the one or more parameters may include a cipher suite, a compression method, an elliptic curve (EC), EC point format, a signature algorithm, a certificate timestamp, etc. The cipher suite may identify, for example, one or more encryption algorithms that the destination device may utilize to connect and/or communicate with the user device 102. In some aspects, the one or more encryption algorithms may include, for example, a key exchange algorithm, a bulk encryption algorithm, a message authentication code (MAC) algorithm, etc. The compression method may identify, for example, one or more transport layer security (TLS) compression methods that the destination device may utilize to connect and/or communicate with the user device 102. The elliptic curve may identify, for example, one or more cryptography schemes that are based on algebraic structures of elliptic curves and may be utilized by the destination device to connect and/or communicate with the user device 102. The EC point format may indicate cryptography keys that may be determined based at least in part on pairs of integer coordinates laying on an elliptic curve and may be utilized by the destination device to connect and/or communicate with the user device 102. The signature algorithm may identify, for example, one or more cryptography algorithms that the destination device may utilize to sign messages transmitted by the destination device to the user device 102. The certificate timestamp may identify, for example, one or more types of certificate timestamps to be signed and transmitted by the destination device while connecting and/or communicating with the user device 102.

Based at least in part on determining the given trusted connection information, the security device 106 may determine a given trusted fingerprint associated with the given trusted source application. In an example, the security device 106 may determine the given fingerprint by hashing and/or encrypting the given trusted connection information. Based at least in part on determining the given fingerprint and/or determining the identity of the given trusted source application, the security device 106 may store, as trusted information, a correlation between the identity of the given trusted source application and the given trusted fingerprint.

The security device 106 may likewise store, as trusted information, correlations between identities of the one or more trusted source applications and respective fingerprints. For example, the security device 106 may store, as trusted information, a first correlation between a first identity of a first trusted source application and a first fingerprint, a second correlation between a second identity of a second trusted source application and a second fingerprint, and so on. In some aspects, the security device 106 may store the trusted information in, for example, the security database 112 that is accessible to the security device 106.

While obtaining the cyber security services during an operation period, as shown by reference numeral 210, the user device 102 may utilize a current source application to transmit a current transmission packet to be transmitted via the firewall to a destination device on the open Internet. The current transmission packet may include an initial connection packet indicating current connection information to be utilized to connect with and/or communicate data with the current source application. The current connection information may include similar and/or analogous other connection information discussed elsewhere herein. For instance, the current connection information may indicate one or more parameters including a cipher suite, a compression method, an elliptic curve (EC), EC point format, a signature algorithm, a certificate timestamp, etc., as discussed elsewhere herein. In some aspects, it may be unknown whether the current source application is affected by malware.

Based at least in part on receiving the current transmission packet, as shown by reference numeral 220, the security device 106 may analyze the current transmission packet to determine an identity of the current source application. In an example, the security device 106 may determine, from the current transmission packet, source information (e.g., source IP address, source port, etc.) associated with the user device 102. The security device 106 may utilize the source information to query the local routing table and/or IP table to determine a process identifier associated with the current source application. Based at least in part on an association between the process identifier and the identity of the current source application, the security device 106 may determine the identity of the current source application.

Based at least in part on determining the identity of the current source application, the security device 106 may analyze the stored fingerprint information to determine an identity of a trusted source application that matches the identity of the current source application. In an example, the security device 106 may compare the identity of the current source application with identities of trusted source applications included in the stored fingerprint information. Further, the security device 106 may determine the stored fingerprint that is stored in correlation with the identity of the trusted source application that matches the identity of the current source application.

Additionally, based at least in part on determining the identity of the current source application, the security device 106 may determine current connection information. In some aspects, the current connection information may indicate information associated with one or more parameters to be used by the current source application and the destination application to connect and/or communicate with each other. As discussed elsewhere herein, the one or more parameters may include any combination of one or more of the cipher suite, the compression method, the elliptic curve (EC), the EC point format, the signature algorithm, the certificate timestamp, etc.

Based at least in part on determining the current connection information, the security device 106 may determine a current fingerprint associated with the current source application. In an example, the security device 106 may determine the current fingerprint by hashing and/or encrypting the current connection information.

As shown by reference numeral 230, the security device 106 may verify the identity of the current source application. In an example, the security device 106 may compare the current fingerprint with the stored fingerprint that is stored in correlation with the identity of the trusted source application that matches the identity of the current source application. Further, as shown by reference numeral 240, the security device 106 may process the current transmission packet based at least in part on a result of comparing the current fingerprint with the stored fingerprint.

When the security device 106 determines that the current fingerprint matches (e.g., is the same as) the stored fingerprint, the security device 106 may determine that the current source application is unaffected by malware. In this case, the security device 106 may route the current transmission packet to be transmitted via the firewall to the destination device on the open Internet.

Alternatively, when the security device 106 determines that the current fingerprint fails to match (e.g., is different from) the stored fingerprint, the security device 106 may determine that the current source application is affected by malware. In this case, the security device 106 may discard the current transmission packet to avoid the current transmission packet being transmitted via the firewall on the open Internet.

In this way, by conducting a verification process to verify an identity of a source application that transmits a transmission packet, and processing the transmission packet based at least in part on a result of the verification process, as discussed herein, a security device may prevent a malicious party from gaining unauthorized access to CSP control infrastructure. As a result, the security device may mitigate effects of private information becoming compromised and/or other hindrances. Additionally, the security device may enable efficient utilization of infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and/or user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) for suitable tasks associated with providing the cyber security services.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

FIG. 3 is an illustration of an example process 300 associated with verifying identity of a source of a transmission, according to various aspects of the present disclosure. In some aspects, the process 300 may be performed by a memory and/or a processor/controller (e.g., processing unit 110, processor 620) associated with a security device (e.g., security device 106). As shown by reference numeral 310, process 300 may include receiving, by a device from a transmitting source application, a transmission packet to be transmitted to a destination application. For instance, the security device may receive, from a transmitting source application, a transmission packet to be transmitted to a destination application, as discussed elsewhere herein.

As shown by reference numeral 320, process 300 may include determining, by the device, connection information included in the transmission packet, the connection information indicating one or more parameters to be utilized by the destination application to connect with the transmitting source application. For instance, the security device may utilize the associated memory and/or processor to determine connection information included in the transmission packet, the connection information indicating one or more parameters to be utilized by the destination application to connect with the transmitting source application, as discussed elsewhere herein.

As shown by reference numeral 330, process 300 may include determining, by the device, a fingerprint associated with the connection information based at least in part on encrypting the one or more parameters.
